Hello,

I have a groupbox that contains 3 radiobuttons. Is there a groupbox
property or some syntax that identifies which radiobutton is checked? Or do
I have to loop?

For Each rad As RadioButton In grpBox1.Controls
If rad.Checked.Equals(True) Then Console.WriteLine(rad.Name)
Next

vs

(pseudo code)
Console.WriteLine(grpBox1.Controls.Checked.Name)


Thanks,
Rich
 
You can use

Select Case True
Case rad1.checked
... do something
Case rad2.checked
... do something
End Select

Add a common event handler to all the radio buttons which belong to a group:

\\\
Private m_Group1SelectedRadioButton As RadioButton

Private Sub RadioButtonGroup1_CheckedChanged( _
ByVal sender As Object, _
ByVal e As EventArgs _
) Handles _
RadioButton1.CheckedChanged, _
RadioButton2.CheckedChanged, _
RadioButton3.CheckedChanged

Dim SourceControl As RadioButton = DirectCast(sender, RadioButton)
If SourceControl.Checked Then
m_Group1SelectedRadioButton = SourceControl
End If
End Sub
